Yellowstone supervolcano may erupt faster than we thought

Yellowstone may be best known for its geysers like Old Faithful, but it's also famous for the supervolcano that lies just beneath the surface. Now researchers from Arizona State University believe the supervolocano last erupted after two influxes of fresh magma flowing into the reservoir beneath the volcano — and it all occurred much more quickly than previously thought. Geologists previously believed it would take centuries for a buildup like that to lead to an eruption.
